The limit is one coupon per one miner.

And you can't use a coupon for a psu.

Ok.
I asked about possibility to do a review, but I haven't received any replies.
I think I'm not exactly their favourite guy after everything I've been talking about.

So I'd say it is safe to say that this will be the final reviewer list:
  • philipma1957 - will get an unit for review, still waiting for a confirmation
  • dimaze - will get an unit for review, already received a confirmation
  • HagssFIN - no replies, out of the game


I recently bought a T9+ unit just for fun and that will most likely be the next machine I'll have a good look at when it arrives.

@gglala
That sounds like a short circuit issue.
1364  Bitcoin / Hardware / Re: DragonMint 16TH/S halongmining.com on: April 02, 2018, 07:25:58 AM
Are they going to send you a free unit, like they are sending to Philip?

That's correct. I had a confirmation email already, it should come this week sometime.

Did they send it so you can make a thorough review here at the forum ?
1365  Bitcoin / Hardware / Re: Antminer V9 4TH on: April 02, 2018, 12:35:05 AM
The price on these things have really come down.  I just bought a used one for $200 and an APW3++ for $200 off Amazon.  This will be my first foray into bitcoin mining and from the research I did there really isn't any cheaper way to get 4TH/s than an Antminer V9.

My electricity rate up here in Canada is 0.04 kWh so I should definitely be seeing profit.

How loud are these miners?

Presumably as loud as the S7 miners are.

Hotmine has the Bitfury BF8162C16 chip listed for sale at $9USD per piece.

What is funny for me, is that I feel that they got angry after I pointed that the control board pcb is very very similar to the Inno one,
instead of just being calm and explaining everybody how the situation is.
1368  Bitcoin / Mining support / Re: antminer s9 feb batch on: April 01, 2018, 10:23:39 PM
so is there way to underclock it?

I'm a simple guy, I give you a simple answer: No.

A longer answer is: Yes, but at a very high risk, you're more likely to break something than to get any real gains out of it. But I have seen some people do it.

Well, you would need to be able to change the PIC firmware to the older S9 version,
there might be some hardware differences (I'm not sure),
and then you might be able to successfull flash an old firmware and have a non-autotune S9.

Another way to go is that you CAN start the autotune frequency search process from a lower point,
when you install new fresh firmware. It is available during first startup in the 'Advanced Settings' section.
So you are able to select 'start frequency search' from either 550M, 600M or 650M.

Yeah, messages received successfully.  Smiley

All three units are now reserved to Zerinoff.


EDIT:
And this is now sold to Zerinoff.  Smiley

I've gotten in touch with Halong and they've agreed to send me a T1 sometime this week for review. I'll have more details and a review when the unit arrives and I get it check it out.

As some of you may remember my previous post, I'm a fairly old school mining enthusiast that has ordered offerings from a good chunk of the well known mining manufacturers. I look forward to reviewing my experience with Halong Smiley

Are they going to send you a free unit, like they are sending to Philip?

They need to prove themselves real and legit before taking any orders..
1373  Bitcoin / Hardware / Re: DragonMint 16TH/S halongmining.com on: April 01, 2018, 12:57:44 PM
<snip> ..as long as they are affordable, perform close to spec and are reliable.
Yeah I agree 100% that in the end it is those things that matter.
1374  Bitcoin / Hardware / Re: DragonMint 16TH/S halongmining.com on: April 01, 2018, 10:51:05 AM
Even the Web UI is just re-skinned/re-shuffled from an existing Inno one: https://i.imgur.com/KzC3RoP.png.


That looks almost IDENTICAL to the Bitmain UI on the S5 miners I used to have and almost NOTHING like the interface on my Innosilicon A2 miners.

Not saying the HARDWARE does or does not have a lot of Innosilicon input or influence, but that UI don't look like Innosilicon at all.

As far as the Dragonmint unit managing over 16 TH in their video, my first guess would be "cherry-picked unit".

Most gold/platinum/titanium rated power supplies don't lose much efficiency from 50% to full load - 3% ballpark is pretty common, sometimes LESS sometimes a bit more.

https://www.techpowerup.com/reviews/EVGA/SuperNOVA_G2_1300/5.html (table at the bottom of the page) for an example - drops from almost 93% at 40% load to a hair over 90 at full rated load or a hair under 90 at 110% of rated load.
@QuintLeo

Halong has reskinned the graphic user interface in their latest version.

The first version of the DragonMint graphic user interface was exactly like in the current generation Innosilicon miners.

Have you seen these comparisons I have made earlier?

Graphic user interface comparison: https://bitcointalk.org/index.php?topic=2443327.msg31724407#msg31724407
Control board comparison: https://bitcointalk.org/index.php?topic=2443327.msg33484292#msg33484292

I think the reason why offordscott has zoomed in the miner status page view might be that he doesn't want the logo "INNOSILICON" be visible in the picture.

Thanks for all this entertainment Sir Theymos.

I see many confused people here.  Cheesy

People please remember it is April Fools day,
and don't get too confused.

My coupons are now all gone.

Happy easter and happy mining for everyone.

These gentlemen who have posted in this thread might still have some 100USD coupons left for give away:
  • philipma1957
  • generalt
  • BenRickert


EDIT:
Added BenRickert to the list, sorry that I forgot you..

@VoskCoin

Thanks for your comments. Smiley

This is all about Canaan Creative and their AvalonMiner hardware. No Bitmain here.

I also have created a separate thread for the AvalonMiner troubleshooting and repair guide. If you are interested to have a look at that, I have the link in my signature space.

Vosk, you should definitely send a message to Steven Mosher (Head of Sales & Marketing) and see if you can work something out with him. Smiley

Steven said he is going to have more training sessions like this in future.

Yep.

As a common notice I just say that those Enermax fans are not providing enough cooling in most situations.

Please don't buy anything less powerful than those Enermax D.F. Storm fans.
Ok noted. Thanks!
So your fan specs should be about in this level area:   enermax d.f. storm <--------       --------> delta electronics qfr1212ghe
